Application led September 22, 1915, Serial No. 52,124. Renewed June 12, 1916. Serial No. 103,342.

To all whom t may concern.'

Beit known that I, WILLIAM Jnssn HENRY FULLER, a subject oftheKing ofGrreat Britain, and resident of'12 Adelaide street west, in the city of Toronto7 county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Gas-Lamps, of which the following is a specification.

The invention relates'to improvements in @as lamps as described inthe present specication and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel construction and arrangement of parts whereby the gas is heated -in its passage from the receiving chamber to the mixing and distributing chamber and inthe novel means for lighting the several burners of the lamp.

The objects of the invention are to facilitate combustion by heating the gas. to economize in the consumption of gas, to produce a gas lamp the parts of which are so arranged as not to cast a shadow on the globe thus producing a soft and even light, to faeilitate the lighting of gas lamps and generally to provide a gas lamp which will he inexpensive to manufacture7 durable and eflicient.

In the drawings, Figure 1 is a view of the lamp complete as it appears when suspended. Fig. 2 is a view of the lamp with the globe removed to show the arrangement of the parts. Fig. 3 is a vertical sectional view through the lamp. Fig. 4: isa. plan view of the lamp with the globeA removed. Fig. 5 is a perspective view of the cylindrical wire gauze used in the mixing chamber. Fig. 6 is a perspective detail of the dish shaped wire gauze used in the mixing chamber.

Like numerals of reference indicate corresponding parts in each gure.

Referring to the drawings 1 is the mixing and distributing chamber being preferably of substantially inverted cup shape and having the inner wall of its open end 2 screw threaded for a. portion of its height and the openings Sin the side wall thereof for the insertion of gas supply pipes to the several burners.

4 is a receiving chamber vformed by the cylindrical neck 5 projecting upwardly from the mixing chamber 1, said neck 5 having its. inner wall converging inwardly adjacent to thel lower end and forming the conical bottom 6 of the said chamber '4.

7 isy a tube screw threaded into the upper end of the neck 5 and forming the suspending rod or stem of the lamp and also forming the connection between the receiving cham-ber and the source of gas supply.

8 is a metal casing suitably ornamented and inclosing the tube 7 to give a more attractive appearance to the lamp.

9 is a T-cock screw threaded into the wall of the neck 5 and having the'horizontal passage 10 therethrough connecting with the receiving chamber l, and the vertical opening 11 extending downwardly from said passage 10.

12 is a valve screw threaded into the outer end of the passage 10 and being for the lpurpose of regulating the supply of gas from the receiving chamber l to the passage 11.

13 is a pipe'having a cone shaped upper end 14 secured in the cup shaped opening 15 in the T-cock 9, said pipe extending downwardly for a considerable distance below the mixing chamber 1 and having screw threaded to the lower end thereof the right angle hollow coupling 16.

17 .is a valve cock having the central opening 18ther`ethrough vand the screw threaded opening 19 through the wall thereof adjacent to thek lower end,'said screw threaded opening 19 being engaged by the hollow couplingl and forming a passage for the gas into said central opening 18.

20 is a cap screw threaded onto the lower ference at its lower end to that of the opening 18 in the valve cock 17 and decreasing to a very small opening at its upper end.

23 is a funnel shaped tube screw threaded at its upper end into the lower end of the mixing chamber 1 and joined at its lower end to the upper end of the pipe 22 and completing the passage from the receiving chamber Lil to the mixing chamber l.

24: is a valve inserted in the valve cock 17 above the opening 19 and being :tor the purpose of shutting olif the supply of gas to the mixing chamber l, said valve having one of its ends slotted in ratchet forma.- tion and being adapted tol be operated by a ratchet lever 25 secured on said valve cock 1'? so that when said lever is drawn down by means of the chain 26 secured thereto the valve will be opened or closed according to its position before drawing down said lever. y ,Y Y

27 is a valve screw threaded into the valve cock 17 above the valve 2a and being for the purpose of regulating the supply of gas to the mixing chamber 1.

28 is a metal ring preferably havingthe outwardly flaring lower end 29 and being adjustably mounted on the pipe 22 adjacent to the lower end thereof and being' adapted to regulate the supply of air to the air slots 30 in said pipe 22.

is a wire gauze encircling the Ainner wall oit the mixing chamber 1 and forming a lining for said chamber.

Aa substantiallyV dish shaped wire gauze adapt-ed to rest on the upper lend of the funnel shaped tube 23 between said tube and the gauze 31.

33 are pipes inserted in the openings 3 in the wall of the chamber 1 for the purpose of supplying gas to the burners 34.

is a T-cock screw threaded into the neck 5 and havin r the horizontal passage' 3G therethrough connecting with the receiving chamber e' and the vertical. passage 37 extending downwardly from said pas` sage 36.

33 is a valve closing the outer end of the passage 36 and regulating the supply of gas to the passage 37.

39 is a pipe inserted in the passage 37 and leading downwardly adjacent to the upper ends of the burners 34 and having secured to the lower end thereof the curved pipe 40, said pipe 4l() having small burners el radiating therefrom to each of the large burners 34, the said burners 41 being always lighted so that when the gas is admitted to the burners 3i they will immediately become ignited by theiiame from the smaller burners 4:1.

42 is a globe of substantially acorn shape mounted on the brackets lf3 on the pipe 8 by' means of the chainslt and being adapted to completely close in from the lower side the lamp mechanism, said globe having the hole Ll5 through its apex for the insertion of the operating chain 2G.

4.6 is a deflector mounted on the pipe S adjacent to the top of the globe 4t2 to prevent the heat or smoke from the burners from discoloring the ceiling or bracket.

ln the operation of this invention it will be seen that before the gas from the receiving chamber can reach the mixing chamber it must pass through the pipe 13 which is in close proximity to the burners 34 and as a consequence it becomes heated and by the time it reaches the said burners it is at the point o combustion. ln its passage through the heated pipe any impurities that may have been in the gas have been removed and consequently a bright and clllcient light is given. The valve 24 affords a very simple and eliicient means of turning onor off the supply of gas to the mixing chamber as the ratchet is so arranged that one* pull on the chain 26 will turn the valve a sufficient distance to open it while the next pull will turn the valve completely around to its former position and close the passage again. A small quantity of the gas from the receiving chamber is continually liowing through the T-cock 35 to the small burners l1 and as these burners are always lighted the larger burners 34 will become ignited simultaneously with the admittance of gas thereto thus providing a convenient and eflicient means of lighting the lamp.
